16．Hello，everyone．First let me introduce myself．My name is Jenny Barker，and I work at St．James Hospital．As most of you know，I'm here today to talk about blood transfusion．The idea of blood transfusion is very simple，but that idea has saved many thousands of lives over the past century．Often，if a person is in an accident，or has an operation，he will lose a lot of blood．And these are times when blood transfusion is needed．This simply means taking blood from another person and putting it into the body of the patient．Doctors have been carrying out blood transfusions for hundreds of years．At first，they used blood from sheep．But that wasn't very successful．It wasn't until the last century that doctors realized there are several types of blood，and that the correct type must always be used．Once they knew that，blood transfusion had become almost a hundred percent successful．So，you might be thinking：what does this have to do with me？Well，it has something to do with all of us．Hospitals need to keep banks of blood ready for transfusion．The only way they can get that blood is from ordinary people like you．All the human body has five liters of blood，and we take 0.5 liters from each person．This is completely safe．In fact，your body will make enough blood to replace it after around a day．Giving blood only takes a short while，and it doesn't hurt．It costs you nothing，and it could save a life．So please give blood．

分析 本文是一篇演講稿，是關(guān)于輸血何獻(xiàn)血話題的演講，其中講了什么是輸血及輸血的發(fā)展過程，最后呼吁人們獻(xiàn)血以挽救病人的生命．

解答 ADBDA
66．A  推理判斷題  本文是一篇演講稿，是關(guān)于輸血何獻(xiàn)血話題的演講，由此可以推知演講人可能是一名醫(yī)生或護(hù)士，故答案為A
67．D 細(xì)節(jié)理解題 根據(jù)This simply means taking blood from another person and putting it into the body of the patient．可以得知這是對(duì)輸血進(jìn)行定義，故答案為D
68．B  細(xì)節(jié)理解題 根據(jù)It wasn't until the last century that doctors realized there are several types of blood，and that the correct type must always be used．Once they knew that，blood transfusion had become almost a hundred percent successful．可知，了解了血型之后，輸血才變得成功，故答案為B
69．D  數(shù)字計(jì)算題 根據(jù)All the human body has five liters of blood，and we take 0.5 liters from each person．This is completely safe．In fact，your body will make enough blood to replace it after around a day．可知，10%就是0.5升，大約一天就可以更新，故答案為D
70．A  推理判斷題 根據(jù)最后兩句Giving blood only takes a short while，and it doesn't hurt．It costs you nothing，and it could save a life．So please give blood．
可以推知，演講者呼吁人們獻(xiàn)血，故答案為A

點(diǎn)評(píng) 做閱讀時(shí)經(jīng)常犯錯(cuò)的主要原因是，僅憑讀過文章后殘留在腦海中的一絲印象來勾選答案，這樣便很容易掉入出題人故意設(shè)布下的題目陷阱．所謂閱讀理解，對(duì)于題目的理解一定要忠實(shí)于原文，因此，每一道題都應(yīng)該與原文作全面的對(duì)比與核查，再得出答案．也就是說，閱讀理解的每一道題目，在原文都應(yīng)該有明確的出處，我們把這一出處叫做原文相關(guān)句，（1）排除與原文相關(guān)句主題不一致的選項(xiàng)（2）排除與原文相關(guān)句態(tài)度相反的選項(xiàng)  （3）排除用于過于極端或負(fù)面的選項(xiàng)（4）注意結(jié)合文章主旨和主題去排除．

7．Wouldn't it be great if you could just look up at the sky and read the weather forecast right away？
Well，you CAN．The forecast is written in clouds．If you can read that writing，you can tell something about the atmosphere．With some practice，you can become a pretty good weather forecaster．Who knows，you might even do as well as meteorologists （氣象學(xué)家）．
Meteorologists use much more information than just the appearance of the clouds to make their forecast．They collect data from all over the world．Then they put it into powerful，high-speed computers．
This does give meteorologists an advantage，because they can track weather patterns as they move from west to east across the country．
But you have an advantage，too．You have your brains．You can look at the sky and get your data directly．A meteorologist uses a computer forecast that's several hours old to make a local forecast．
What are you seeing when you look at a cloud？"A picture of what moisture （水氣） is doing in the atmosphere，"says meteorologist Peter Leavit．There's moisture throughout the atmosphere．Most of the time you don't see it，because it's in the form of an invisible gas called water vapor．
    Sometimes，the temperature of the air gets cold enough to cause the water vapor to change to liquid water．That's called condensation，and we see it happen all the time，for example，when humid air from the shower hits the cold glass of a mirror．When enough water vapor condenses，droplets form in the air．These droplets scatter light．A cloud is seen．
Watching clouds over a day or two tells you a lot more than a single cloud about the weather to come．Changes in clouds show changes in the atmosphere．
You should begin to notice patterns．Certain clouds，fol1owing each other in order，can signal an approaching storm．But don't take our word for it； see for yourself．
53．According to the passage，ordinary people can tell the weather becauseD．
A．they can look up at the sky                         
B．they can read weather writings
C．information is stored in computers              
D．clouds signal the weather to come
54．Your advantage in weather forecast is thatC．
A．you can keep weather patterns in mind．
B．you have more powerful computers at home
C．your brain works as well as a high-speed computer
D．meteorologists give their data to you as soon as they get them
55．A cloud is formed whenA．
A．there are droplets in the air                        
B．light is scattered
C．moisture exists in the form of invisible gas  
D．water vapor changes to liquid water
56．This passage mainly tells us about howD．
A．to become a weather forecaster                   
B．to collect data directly
C．to be an assistant to a meteorologist             
D．to keep an eye on the weather．

The next Saturday afternoon，Mauson asked some policemen to come to the house．They were told that the real firebug would be shown there．At that time，the sun was shining full into the house and it became hotter and hotter inside the room．"Now，"said Mauson，"this house will soon catch fire．"People looked at each other in surprise．Mauson asked them to look at the bottles and focus on the table cloth．After a while the cloth gave off a burning smell and began to catch fire!

5．People living more than three thousand meters above sea level find it difficult to raise vegetables all year long．People living in the highlands of Peru and Bolivia，for example，cannot grow vegetables outdoors during the months of May through September．It is very cold in the highlands at that time of year．If traditional farming methods are used，vegetables will not survive．
However，there is another way to grow vegetables throughout the year in cold areas．It is a method of gardening developed by a private agency called World Neighbors．The method uses"hot houses"built below ground．A hot house is a building covered with plastic or glass in which vegetables or flowers are grown．The traditional hot house is built above ground．
The air temperature is cold in the highlands of Peru and Bolivia during the winter．But，the winter sun is hot．So，World Neighbors advises farmers there to build hot houses below ground．The design is simple．The material does not cost much．Here is how World Neighbors says to build it：Dig a hole two and one-half meters wide and six meters long．Make it about two meters deep．Build wall with a door in one end of the hole．Dig steps from the ground down to the door．
Now，build a wall along the top edge of the hole．Make it about one-half meters tall．Earth bricks work fine．Build two shorter walls on the ends．These will be uneven； one side will be as high as the existing wall．The other side will be at ground level．Leave a small opening in each of these sloping walls．This prevents the hot house from becoming too hot．Now，make the roof．Build a wood frame．Cover it with clear plastic．Connect it to the brick walls．
The underground hot house we have described is large enough for two raised vegetable beds．Each is one meter wide and six meters long．Each is seeded and watered just as if it were in a garden above ground．
The dirt walls protect the growing plants from the cold．The clear plastic roof permits the sun's heat to enter．At night，the roof should be covered with straw．This helps prevent cold air from entering．An under ground hot house this size will provide enough vegetables for one family．Groups needing more vegetables can make it bigger．

66．If you lived in Peru，youC．
A．should raise the special kinds of vegetables that can endure cold
B．could not plant at all
C．had to work out some new unusual plans
D．would not have many vegetables to eat
67．To our surprise，the"hot houses"invented by World Neighbors areB．
A．covered with a transparent plastic ceiling
B．built under ground
C．quite small
D．hotter than traditional ones
68．The hot house can be kept warm by usingD．
A．a(chǎn) big oven
B．a(chǎn)n electricity heater
C．the heat of the earth's interior
D．the sun shine
69．The measure to prevent the hot house from becoming too hot is toB．
A．make the roof sloped
B．dig holes on the walls
C．make the wall not vertical
D．make the walls shorter than the ground level
70．According to the passage，the method suggested by World Neighbors isD．
A．new and difficult     B．uneasy to explain
C．a(chǎn)t trial step         D．simple and practical．
